Non-powdery solid sterilization oxygenation agent

Technical field

The present invention relates to a kind of non-powdery solid sterilization oxygenation agent.More specifically say, be a kind of be the non-powdered different shape of effective constituent and the solid sterilizing oxygenation agent of size with the SPC-D.

Background technology

The sterilizing agent that custom is used on the existing market is with the disinfection sanitizer of chlorine as effective constituent mostly.Though this series products disinfection effect is fine,, all can produce pungent smell in preparation and use, its residue does not meet environmental requirement yet.In addition, along with the raising of people's living standard or because of disease, some people needs supplemental oxygen in the family, and still, traditional dependence oxygen cylinder oxygen supply is very inconvenient.In modern aquaculture, high-density breeding and subatmospheric regular meeting cause the aquaculture water anoxic, thereby cause the general pool and floating head.Usually adopt mechanical stirring oxygenation, but can only solve the local anoxic of water surface, and can't make whole water body, particularly deep water body oxygenation.In recent years utilize powdery sodium percarbonate meet water can oxygenous performance as sterilization oxygenation agent, but powdery sodium percarbonate easily flies upward in use, inconvenience is carried, be difficult for metering, at water float, is difficult to make the even oxygenating of whole water body.These disadvantages affect applying of it.A kind of method with the powdery sodium percarbonate moulding is arranged in the market, though overcome the powdered shortcoming, but for guaranteeing moulding, the auxiliary substance relevant with moulding that adds in moulding process is too much, account for 3～70% of preparation total amount, like this, make the user spend money on more non-active ingredients on the one hand, these auxiliary substances too much can bring again because of the too much series of malpractice that produces of residue on the other hand.

Summary of the invention

The objective of the invention is to, a kind of non-powdery solid sterilization oxygenation agent is provided, improve active constituent content, do not influence the firmness of solid, reduce residue.

Realize the technical scheme of the object of the invention: a kind of non-powdery solid sterilization oxygenation agent, it is with SPC-D 2Na ₂CO ₃3H ₂O ₂Be effective constituent, it is characterized in that: the weight percentage of each component is: median size is the sand shape SPC-D 97～99% of 0.12～1.0mm, binders pregelatinized starch 0.8～2.0%, stearic acid release agent magnesium 0.2～0.8%, disintegrator carboxymethylstarch sodium 0～1.0%, pregelatinized Starch is earlier at aforesaid SPC-D particle surface coating and dry, again with aforesaid Magnesium Stearate, the moulding of carboxymethylstach sodium mixing.

Above-mentioned solid sterilizing oxygenation agent, the shape of described non-powdery solid is the sheet of different shape, spheroid, spheroid, right cylinder, rectangular parallelepiped, prism, round platform or circular cone.Can select solid shape and size according to purposes and client's needs, molding device only need be changed difform profiled part and get final product, and is convenient and simple.

Technique effect of the present invention: in the technical scheme of the present invention, with median size is that the sand shape SPC-D of 0.12～1.0mm is made raw material, replace Powdered SPC-D of the prior art (median size is less than 1.0mm), and be used as the pregelatinized Starch parcel sand shape SPC-D particle of tackiness agent earlier, make its surface form a kind of film and dry, and then with other component mixing moulding.Like this, a little binder just can be brought into play the adhesive effect of tackiness agent when moulding, and binder dosage is 0.8～2.0% consumption far below prior art (2～35%), has reduced cost, reduces residue.Simultaneously, the SPC-D particle of coating, during further processing, the film of particle surface also avoids the percarbonic acid steel to contact with other objectionable constituent such as iron, heavy metal etc., has guaranteed the stability of SPC-D, and then guarantees its oxygenation effect of sterilizing.Therefore, the present invention only uses minor amounts of auxiliary substances (accounting for 1～3.8%) just can make SPC-D make the solid sterilizing oxygenation agent of different shape and size, improve active constituent content and sterilization oxygenation effect, reduced residue, also do not damaged the firm degree of solid substance.

Embodiment

Below in conjunction with embodiment the present invention is further described in detail, but is not limited to this.
